Further north, a Winter Storm Warning will be in effect until 6 a.m. Wednesday for counties in northeast Indiana and southwest Michigan. The weather service said those areas could see 4-6 inches of snow and strong, gusty winds.

Chicago continued preparing for the winter weather Tuesday.

The city's 19 salt piles are stocked and ready for Department of Streets and Sanitation trucks to fill up.

Chicago has about 370,000 tons of salt available this year.

But there is some good news. Temperatures will approach 40 degrees by this weekend.
